You need to be very careful with comparison sites.
I am currently with BG for both fuels and know exactly what I consume and the tariff rate pay
I compared my rates with Sainsbury Energy and established that I could save £100 per year before paying a penalty of £60 for early exist, so a net saving of £40/year.
The comparison site used my exact same tariff and consumption figures and established that the very same Sainsbury site on the very same tariff that I identified would net me a saving of £360/year. Clearly a con to get me to change so's they could collect the transfer fee.
